Wow, thank you! That really helps.
I'm hoping to have a chance to tear back into it sometime next week. Tonight I found a wet spot on the pass-side floor mat, so it looks like I'll be doing a heater core soon. So while I have my tools out and some of my interior apart, I'll go ahead and ohm out those circuits.
If you're going into the dash, I'd find the ICM box, and "ohm my way back" to the switch.
It's on the driver's side, left of the column; maybe part of the fusebox, or real close. (can't tell from pic)
That harness goes thru connector C2022 (Yellow) behind the panel, to the left of the column.
DB/W pin 17
BR/W pin 7
O pin 6
These are the second pins from the end with a missing pin (18), and the orange wire is beside the BR/W wire.
At the ICM box, they're on C242.
These are the pin numbers:
DB/W pin 7
BR/W pin 1
O pin 8
It could be the box, too.
Additional stuff, somewhat related:
This box is on the 30A "Wipers" fuse. possibly #27
There's a separate park relay (BK/PK) in the ICM box, and it's own ground wire at the wiper motor.
